When statistical evidence is not specific enough

Synthese - Many philosophers have pointed out that statistical evidence, or at least some forms of it, lack desirable epistemic or non-epistemic properties, and that this should make us wary of...     

May the odds be ever in your favor: The Hunger Games and the fight for a more equal society. (Negative) Media vicarious contact and collective action

Various studies have found that reading books about positive interactions between ingroup and outgroup characters, known as media vicarious contact, can reduce prejudice. Focusing on the fantasy saga of The Hunger Games, we examined the effects of negative vicarious contact on collective action across two studies. Specifically, we tested whether reading about fantasy characters living in a postapocalyptic conflictual society with large social disparities between advantaged and disadvantaged groups leads advantaged group members to display greater willingness to engage in collective action on behalf of the disadvantaged group. Results from Study 1 (correlational survey in the United Kingdom and United States) and Study 2 (experimental intervention in Italy) revealed that reading The Hunger Games is indirectly associated with greater collective action intentions via increased anger toward injustice. In both studies social dominance orientation (SDO) acted as a moderator, but in opposite directions: mediation was significant for low-SDOs in Study 1, and for high-SDOs in Study 2. Results are discussed in relation to the importance of media vicarious contact via book reading for social change, and to the need to identify the contextual conditions allowing to anticipate the specific moderation pattern that is more likely to emerge.     

Pathways to prejudice and outgroup hostility: Group alignment and intergroup conflict among football fans

How do different forms of group alignment influence our attitudes toward outgroups? To answer this, the current fieldwork study explored how identification and identity fusion differentially impact outgroup anxiety, prejudice, and hostility toward rival football fan supporter groups in Australia. The community participants (N = 100) were members of two active fan groups who had experienced a history of intergroup tensions. The findings from the full path model confirmed that the predictor group alignment variables of identification and fusion were correlated, and the two outcome variables of outgroup prejudice and hostility were correlated, as predicted. The findings also revealed that fusion with one's club predicted outgroup hostility, but not prejudice, whereas identification with one's club predicted outgroup prejudice, but not hostility. Additionally, outgroup anxiety was found to significantly mediate the relationship between ingroup identification and outgroup prejudice, whereas a similar relationship was not found for fusion. These findings highlight the differential impact of group alignment (i.e., identification and identity fusion) on social constructs of outgroup anxiety, prejudice, and hostility. Empirically, this is the first study to demonstrate the workings of these distinct group alignment pathways in an applied setting involving hard-core football fans. We discuss the broader implications of these findings for a fuller understanding of the drivers of intergroup tensions and conflict.     

Preference for Human (vs. Robotic) Labor is Stronger in Symbolic Consumption Contexts

Advances in robotics, automation, and artificial intelligence increasingly enable firms to replace human labor with technology, thereby fundamentally transforming how goods and services are produced. From both managerial and societal points of view, it is therefore important to understand demand‐side incentives for firms to employ human labor. We begin to address this question by examining for which products and services consumers are more likely to favor human (vs. robotic) labor. In six studies, we demonstrate that consumers prefer human (vs. robotic) labor more for products with higher (vs. lower) symbolic value (e.g., when expressing something about one's beliefs and personality is of greater importance). We theorize that this is because consumers have stronger uniqueness motives in more (vs. less) symbolic consumption contexts (and associate human labor more strongly with product uniqueness). In line with this account, we demonstrate that individual differences in need for uniqueness moderate the interaction between production mode and symbolic motives and that a measure of uniqueness motives mediates the effect of consumption context on preferences for human (vs. robotic) production.

Opposite strain-dependent differences for intermale aggressive behavior elicited by individual housing and housing with a female in the mouse

Male mice of the C57BL/6 strain show a significant increase in aggression toward a nonaggressive male conspecific following 72 hr of individual housing. However, this increase was no longer evident following 2 weeks of individual housing. When housed with a female, C57BL/6 mice show significantly more aggression than singly housed mice of the same strain after 72 hr as well as 2, 4, 8 weeks of differential housing. Male C57BL/6 mice housed with a female also show significantly higher levels of aggression than DBA/2 mice living in the same housing condition after 4 or 8 weeks of differential housing. Finally, male DBA/2 mice individually housed for 8 weeks are significantly more aggressive than mice of the same strain housed with a female for the same time. These results indicate that the increase in aggressive behavior observed following isolation and cohabitation with a female in the mouse is not the same phenomenon. © 1994 Wiley-Liss, Inc.     

Variation in aggressive behavior and anatomo-physiological correlates generated by crowding without physical contact in the house mouse

Behavioral, physiological (i.e., endocrine), and anatomical consequences of crowding in mice were studied in a situation where animals were in auditory, visual, olfactory, and tactile contact but restrained from full physical interactions, to prevent overt aggression. Males that cohabited with females undisturbed by neighboring conspecifics showed greater propensity to attack same-sex intruders and had higher plasma testosterone levels than did their “crowded” counterparts, that is, males cohabiting with females and housed adjacent to other male/female pairs. In this respect, the latter animals resembled submissive males. However, a significant increase in weight of androgen-dependent target organs (i.e., seminal vesicles and preputial glands) was found in crowded males. These data indicate that despite the observed inhibition of social aggression these males are not physiologically comparable (homologous) to male mice that experienced defeat and the stress of submission during fighting. The intriguing possibility that different conversion pathway of testosterone are accelerated, as a result of social communication, in males living in these two environments and the behavioral implications of these possibilities are discussed. Finally, the parental behavior of crowded animals, although not freely interacting with each other, was disrupted, causing a marked decrease in reproductive success. In this situation a high incidence of infanticide of their offspring by both parents was observed, whereas this behavior was virtually absent in non-crowded male/female pairs.     

Does inconsistency always lead to negative affect? The influence of need for closure on affective reactions to cognitive inconsistency

We present an experiment showing that need for closure (NFC)—defined as the epistemic desire for certainty—can moderate individuals' affective reactions to cognitive inconsistency. Informed by Kruglanski and colleagues' new theory, that cognitive inconsistency elicits negative affect particularly under certain circumstances, we find that NFC (i.e. the desire for certain, stable and unambiguous knowledge) influences the strength of consistency effects and resulting negative affect. More specifically, we find that individuals who are high on NFC experience more negative affect upon encountering an inconsistent (vs. consistent) cognition. However, when individuals are low on NFC, inconsistency is irrelevant, and their affect depends on whether the ultimate outcome of the cognition is positive or negative. We discuss the theoretical and practical implications of this research.     

Sympathy as knowledge of the other in need: An investigation into the roles of need for closure and the moral foundations on sympathy toward immigrants

Although sympathy is a powerful other-focused motivation, not all individuals will experience sympathy when it is appropriate. Immigrants, as a disadvantaged out-group, are especially in need of sympathy and, given the tensions of the immigration debate, are at-risk for low sympathy. Indeed, past research has found that sympathy is less likely to be experienced toward disliked out-groups. In the current research, we investigated the role of need for closure (NFC), or the general desire for epistemic certainty, on the experience of sympathy toward immigrants in Italy, a nation where the immigration debate is becoming increasingly fractious. Consistent with past research on the roles of NFC and the binding moral foundations (i.e., a concern for the well-being of groups) on prejudice toward out-groups, we propose that individuals with a high NFC, and who endorsed the binding moral foundations (i.e., a concern for the well-being of groups), would be particularly likely to have decreased sympathy toward immigrants in Italy. In line with past research and our hypotheses, in three studies we found that the binding foundations mediated the NFC effect on decreased sympathy toward immigrants in Italy. Conceptually, these individuals can strongly adopt traditional cultural norms as a way to acquire stable knowledge; this can make sympathy toward immigrants less likely, as they both stand outside “traditional” morality, as well can threaten the stability of natives’ knowledge.
